That is correct. The fuse really is the first line of defense in electrical devices. It is quite interesting to note that some power supply devices used for electronics do not have screws in their case and are sealed by adhesives, making the fuse difficult to replace should it be destroyed, while some devices have a special capsule with a screw and a dial protruding out of the device's case that can be unscrewed so that the fuse inside can be quickly replaced. Why not put this type of feature on all devices? Is it to force consumers to buy new power supplies costing tens of dollars rather than just replacing a fuse which only costs cents?
